[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figures 1 to 4 A metering box with a detachable neutral busbar clamp includes a box body 1, a neutral busbar 2, a neutral busbar clamp 3, a quick-release assembly, neutral wire through holes, a quick-release plate 4, a quick-release assembly, and an insulating pad 5. The neutral busbar 2 is detachably connected to the inner wall of the box body 1. Two connecting screws are symmetrically threaded between the neutral busbar 2 and the inner wall of the box body 1, facilitating quick installation and removal of the neutral busbar 2 inside the box body 1. The neutral busbar clamp 3 is detachably connected to one side of the neutral busbar 2. The quick-release assembly is disposed between the neutral busbar clamp 3 and the neutral busbar 2. Multiple neutral wire through holes are provided. The wires are linearly distributed on the neutral wire clamp 3, which facilitates the separate threading and insertion of multiple neutral wires. Multiple quick-release plates 4 are provided, and the multiple quick-release plates 4 are respectively movably set at the multiple neutral wire through holes. The neutral wire clamp 3 has a moving cavity for the quick-release plates 4 to move, which facilitates the position adjustment of the quick-release plates 4. Thus, two adjacent quick-release plates 4 can clamp and fix neutral wires of different specifications. Multiple quick-release components are provided, and the multiple quick-release components are respectively set between the multiple quick-release plates 4. The insulating pad 5 is fixedly connected to each quick-release plate 4, which can stably contact and clamp the neutral wire.

[0045] refer to Figure 3 as well as Figure 4The quick-release assembly includes a connecting frame 6, threaded strips 7, an adjusting seat, an adjusting plate 8, and an adjusting post 9. The top of the zero-row cable clamp 3 has a connecting groove that matches the connecting frame 6. There are two threaded strips 7, both of which are rotatably mounted inside the connecting frame 6. The two threaded strips 7 have threads in opposite directions. Each threaded strip 7 is fixedly connected to a limiting post 18. The inner side wall of the connecting frame 6 has a limiting groove for the limiting post 18 to rotate, which facilitates limiting the rotation of the threaded strip 7 within the connecting frame 6 and improves the stability of the threaded strip 7's rotation. The adjusting seat is located between the two threaded strips 7. The adjusting plate 8 is threadedly connected to each threaded strip 7. The zero-row cable clamp 3 has an adjusting groove for the adjusting plate 8 to slide. The adjusting post 9 is fixedly connected between each adjusting plate 8 and the adjacent quick-release clamp plate 4. Two symmetrically connected stable blocks 17 are connected to the adjusting plate 8. The connecting frame 6 has a stable groove for the stable blocks 17 to slide, which allows the adjusting plate 8 to move smoothly in the adjusting groove, thereby allowing the adjusting post 9 to drive the zero-row cable clamp 3 to move smoothly.

[0046] When two adjacent threaded bars 7 rotate, the two adjusting plates 8 connected to the two threaded bars 7 can move towards each other. At the same time, the two adjacent adjusting columns 9 will drive the two adjacent quick clamping plates 4 to move towards each other. By adjusting the position of the quick clamping plates 4, the two adjacent quick clamping plates 4 and the two insulating pads 5 can stably clamp the neutral wires of different specifications, thereby improving the stability of the neutral wires during use.

[0047] refer to Figure 4 The adjusting seat includes an adjusting rod 10, an adjusting bar, a main gear 11, a driven wheel 12, and an adjusting rotating plate 13. The adjusting rod 10 is fixedly connected between two adjacent threaded bars 7. The adjusting bar is rotatably mounted on the connecting frame 6. The main gear 11 is fixedly connected to the adjusting bar. The driven wheel 12 is mounted on the adjusting rod 10, and the main gear 11 meshes with the driven wheel 12. The adjusting rotating plate 13 is fixedly connected to the top of the adjusting bar, and a cross groove is provided at the top of the adjusting rotating plate 13.

[0048] When a cross cutter or other tool is inserted into the cross groove, the adjusting plate 13 can be rotated. At the same time, the adjusting plate 13 will drive the main gear 11 to rotate through the adjusting bar. At this time, the adjusting rod 10 can be rotated through the meshing of the main gear 11 and the driven wheel 12, so that the adjusting rod 10 can drive the two threaded bars 7 to rotate stably.

[0049] refer to Figure 1 as well as Figure 2The quick-release assembly includes a quick-release bracket 14, a quick-release block 15, and a quick-release screw 16. There are two quick-release brackets 14, which are symmetrically connected on both sides of the neutral busbar 2. There are two quick-release blocks 15, which are symmetrically connected on each quick-release bracket 14. The quick-release blocks 15 have grooves that match the neutral busbar 2. The quick-release screw 16 is threaded between each quick-release block 15 and the neutral busbar 2.

[0050] After multiple quick-release blocks 15 are respectively snapped onto the neutral busbar 2 through multiple grooves, multiple quick-release screws 16 are tightened between the neutral busbar 2 and the multiple quick-release blocks 15. This can stably fix the multiple quick-release blocks 15 on the neutral busbar 2, so as to facilitate the quick installation of the two quick-release brackets 14. This facilitates the quick and stable installation of the neutral busbar clamp 3 on one side of the neutral busbar 2, and at the same time, the neutral busbar clamp 3 can be quickly disassembled on the same side of the neutral busbar 2.

[0051] In summary, the metering box with detachable neutral wire clamps first attaches multiple quick-release blocks 15 to the neutral wire busbar 2, and then tightens multiple quick-release screws 16 between the neutral wire busbar 2 and the multiple quick-release blocks 15. The quick-release frame 14 is then quickly installed on the neutral wire busbar 2, allowing for quick and stable installation of the neutral wire clamp 3 on one side of the neutral wire busbar 2. Then, multiple neutral wires are inserted into multiple through-holes and connected to the neutral wire busbar 2. Multiple adjusting plates 13 are then sequentially tightened, causing the adjusting bar to rotate the adjusting rod 10 through the meshing of the main gear 11 and the driven wheel 12. Simultaneously, the adjusting rod 10 drives two adjacent threaded bars 7 to rotate, causing two adjacent adjusting plates 8 and two adjusting columns 9 to move two adjacent quick-release clamping plates 4 towards each other. This allows the adjacent quick-release clamping plates 4 and two rubber pads to quickly clamp the neutral wires, thus enabling the separate clamping and fixing of multiple neutral wires and improving the stability of the neutral wires during use.
